Jabs... Am I seeing an "L4" below the click gear? I'm noting our movement database, albeit incomplete, as having one date for 7AA. I'll try to update movement database based on subject watch, and a couple other 7AA examples in that date range. Sure looks like your watch matches the 1955 ad you posted in root record. Good ad match, and nice watch. Keep these beauties coming. They help flush out our database.
